Dvorak Assistant

Function for left-control Z, X, C & V (for general windows copy, cut,
paste, undo functions) would be great. So would too win-E, L, R, etc.
Maybe an option to allow use of these two keys in combination with qwerty
keys?

You mean, when keydown on Left-Ctrl/Windows Key happens, switch to Qwerty,
then back to Dvorak on key-up? Agreed - that would be cool. I'd have to get
the keyboard hook working -- been years since I tried, but last attempts
weren't too successful, unfortunately. Probably programmer error :-/
